The answer is D. If you divide 7 by 5, you'll have a remainder of 2. If you divide 8 by 5, you'll have a remainder of 3, and if you divide 9 by 5 you'll have an remainder of 4. And respectively just means in order ..
0 = x^2 + x - 72
x^2 + x - 72 = 0
x^2 + 9x - 8x - 72 = 0
X (x + 9) - 8 (x + 9) = 0
(X + 9) (x - 8) = 0
X + 9 = 0
X = -9
X - 8 = 0
X = 8
X (-9,8)
Answer is Option D
x = -9 or x = 8
Answer:
